Simec Atlantis Energy has unveiled a design for a new 2MW tidal power turbine that can accommodate rotor diameters of between 20 and 24 metres. 

The company said the AR2000 will have a maximum output of 2MW at 3.05 metres per second using a 20-metre rotor.

Development of the AR2000 has taken place over the last two years and builds on lessons learned from the AR1500 model deployed at the MeyGen project in Scotland.

Simec Atlantis said the new design is offered as part of a complete rotor-to-grid tidal generation system, including array architecture that allows for multiple turbines to be connected in parallel.

AR2000 will feature a new electro-mechanical pitch system, 360 degrees of yaw, upgraded health monitoring and diagnostics and critical system redundancy.

Simec Atlantis director of turbine and engineering services Drew Blaxland said: “The AR2000 marks the culmination of 15 years of investment, relentless experimentation, rigorous testing and subsea operation.

“Not only will it be the largest single rotor turbine in production, it will be the backbone of a highly efficient and cost-effective generation system capable of deployment in each of our key markets in the UK, France, Channel Islands, Asia, Australia and Canada.”
